I am a nymph fisherman and use Sage WF fly line in a light yellow color. I concentrate on watching the fly line so hard that I am not aware of anything going on around me. I do not like using an indicator and have been told that I am a very good nymph fisherman.

I experimented with some WF Sinking line over the weekend, for use on ponds and lakes, and would like to know how you detect "hits" on it. The line I am using is black in color and very hard to see. Would I be correct to assume that when fishing sinking fly line that you fish by "feel" instead of line watching? Thanks for your input on this.
